PRESS FOR SHARING AND ORNAMENTING HOLLOW METAL ARTICLES.

SPECIFICATION forming part of Letters Fatent No. 465,836, dated December29, 1891.

Application led October 19, 1891. Serial No. 409,189. (No model.)

To @ZZ whom vil? may concern.-

Be it known that I, THOMAS WALTER CREES, a subject of I-I er Majesty theQueen of Great Britain and Ireland, residing at Birmingham, county oflVarwick, England, have invented a new and useful Improvement in Pressesfor Shaping and Ornamenting Hollow Metal Articles; and I do herebydeclare the following specification, ,taken in connection with the accompanying drawings, forming a part of the same, to be a descriptionthereof.

This invention relates to a press for shaping and ornamenting, either inrelief or intaglio, hollow articles of metall-such, for instance, ascaneheads, cream -pitchers, sugarbowls, and a large variety ofmanufactures in gold, silver, tbc., which are made of thin or sheetmetal. Y

The invention consists in certain features of construction andarrangement, hereinafter described and claimed.

In the drawings, Figure l represents a face or front View of a pressembodying the invention. Fig. 2 shows a horizontal section of the sameon line XXof Fig. l. Fig. 3 represents,

' on a much larger scale, a transverse section of the press online Y Yof Fig. 2. Fig. a shows in perspective, on a still larger scale, a plainmetal can e-head prior to being operated upon by the press. Fig. 5 showsthe same after it has been ornamented in relief or given its iinal shapeby the press.

The press consists of a body A, which may be mounted on suitable legs ormay be furnished with ears ce, through which bolts or screws can pass tosecure the press to a bench or platform, as B. This body is providedwith a cavity C, opening from the front, and below this cavity isarranged a cavity D, circular in outline, by preference, and tapering,so as to be smaller at the bottom than at the top. The cavity D isintended to receive a die E, made, by preference, in the shape of thefrustum of a cone and in two or more parts, three being shown in Fig. 2.On the interior of the die E is cut the mold or cavity e, that is togive the shape and ornament to the hollow metal article to be made, thesaid mold or cavity e being open at the top.

The article Fvto be made (say a cane-head) is in any preferred andproper manner first given its general shape, as shown in Fig. 4. Itsinterior is then properly packed or filled with some suitable materialor substance G, Fig. 3, having the proper density and capacity fordisplacement-such, for instance, as gutta-percha. The article is thenplaced in the die-mold c and the die is passed into the cavity C andlowered in to the cavity D, where it will rest, substantially as shownin Fig. l.

For seating the die E in the cavity D, and thereby bringing the dieparts into as close a relation as possible and holding them so, suitablemeans are employed, such as a screw II, to the upper end of which awheel I-I is secu red, the screw being threaded through the upperportion of the bodyof the press. Vhen the screw H is loweredsufficiently, the die E will be forced tightly into the cavity D, andthe lower end or part h of the screw (the face of which end is parallelwith the upper surface of the die and of the proper size or area) willclose and seal the upper end or mouth of the mold or cavity e, as shownin Fig. 3, and thereby prevent the escape of any of the packing G duringthe subsequent operation. The article F is forced Vto conform to theinold e, and its shape and ornamentation thereby determined by thedisplacement of the packing or liing G. This displacement is secured bythe descent into the packing of a plunger K, which is of a proper sizeto enter the article Fand works in the longitudinal axis of the screw IIthrough a closely-fitting hole it in the lower end of said screw. Theplunger K' is mounted on the lower end of a screw L, which is threadedinto the screw H and has a wheel L at its upper end. Preferably theplunger K is swiveled on the screw L, so as not to rotate with the screwwhen the plunger is in engagement with the packing G, and this swivelconnection may be secured by passing the upper end K of the plungerthrough a hole m in a block M and rotatively securing the plunger to theblock by a nut or fastening 7s, then securing the block M to the screwL, as by screwing the block into the screw, as shown in Fig. 3. Foreconomy of time both the screws H and L may be made to descend togetherfrom the position shown in Fig. l and holding the same relation as shownin said figure. Then the screw H has seated the die IOO and sealed themouth of the mold c, the screw L is made to descend still farther,thereby forcing the plunger K into the paekingG and displacing itlaterally or radially and causing the article F to take the shape andornamentation of the mold e. The plunger is withdrawn by raising thescrew L, when both the screws H and L are raised to the position shownin Fig. l.

For starting the die E out of the cavity D and raising the die so thatit may be grasped and removed from the press, suitable means areemployed, such as a screw H, having a wheel N on its lower end andthreaded through the lower portion of the body of the press, andpreferably supplied with a plate n, Fig. 3, swiveled to its upper end.The screw N also furnishesa convenient means for lowering the die intothe cavity D, as will be readily understood. When the die has beenraised by the screw N, it is removed from the press, opened, and thearticle F, completed, as shown in Fig. 5, for instance, is taken fromthe die. The filling or packing G is then removed from the article andmay be used again.

My improved press is very eicient in action, and by its use articles ofthe character described can be shaped and ornamented with great accuracyand success.

Vhat I claim as my invention, and desire to secure by Letters Patent,is-

1. The combination, with the press-body having a tapering die-supportingcavity, of a screw in alignment with said cavity for seating the dietherein and sealing the mouth of the die-mold, a plunger working throughsaid screw, and a lever attached to the plunger for reciprocating thesame, substantially as and for the purposes specified.

2. The combination, with the press-body having a tapering die-supportingcavity, of a screw in alignment with said cavity for seating the dietherein and sealing the mouth of the die-mold, a plunger working throughsaid screw, a screw attached to the plunger for reciprocating the same,and a screw in alignment with the die-cavity for starting the die andraising it from said cavity, substantially as set forth.

3. rIhe combination, with the press-body having a taperingdie-supporting cavity, of a Screw in alignment with said cavity forseating the die therein and sealing the mouth of the die-mold, a plungerworking through said screw, and a screw swiveled to the plunger lforreciprocating the same, substantially as forth.

il. 'lhe combination, with the press-body THOMAS WALTER CREES.
